pacecars, I thought real hard about the 40-90 SBN, my idea of a lot of potential fouling with 16 twist and 90 grains of powder, not to mention the sight correlations would be really close together on the barrel sights for a hot rod round that shot so flat, and last but not least, I love big bores and heavy bullets.

Nuclearcricket and John, right on all counts, I talked to Kirk up at Shiloh today, I'll mail him a couple sized cases to go with my order number build, he'll cut the groove for my brass, I went through and measured them all, picked out two of the fattest ones to send.
